2 Claims. 1

This invention relates to improvements in a bobby pin spacing device adapted for use in arranging a plurality of bobby pins in spaced parallel relation along a notched bar; after which, the bobby pins are transferred from the notched bar onto an oven Wire for subsequent manufacrturing operations, such as tempering, japanning and carding.

Itis an object of this invention to provide a device of this type in which a plurality of bobby pins are mounted on the upper end of a notched bar disposed in an inclined plane upon a suitable tray which, in turn, is mounted upon a reciprocable carriage. During reciprocable movement of the carriage, the bobby pins are rocked laterally on the notched bar and caused to move longitudinally therealong and into spaced parallel relation Within their respective individual notches.

It is a further object of this invention to provide a bobby pin spacing device which is relatively simple in operation, inexpensive in construction and which will not readily get out of order.

This invention embodies other novel features, details of construction and arrangement of parts which are hereinafter set forth in the specification and claims, and illustrated in the accompanying drawings wherein:

Fig. 1 is a plan vievv, looking along the line I-I of Fig. 4, illustrating a bobby pin spacing device embodying features of this invention.

Fig. 2 is an enlarged fragmentary sectional view taken along the line 2-2 of Fig. l.

Fig. 3 is a front elevational view illustrating a bobby pin spacing device.

Fig. 4 is a side elevational view of same.

Fig. 5 is an enlarged fragmentary detail view illustrating the manner in which bobby pins are moved longitudinally down the inclined, notched bar and into spaced parallel relation within their respective individual notches.

Fig. 6 is a sectional view taken along the line 6-6 of Fig. 5.

Fig. 7 is a detail sectional view illustrating the manner in Which the bobby pins are mounted upon an oven Wire.

Referring now to the drawings for a better understanding of this invention, the bobby pin spacing device is shown as comprising a base B preferably formed of angle-iron and supported in an inclined plane upon suitable angle-iron legs 'I. A pair of carriage supporting rails 8--8 are mounted in spaced parallel relation upon the base 6 to support a carriage 9 which is also pref- CII erably formed of angle-iron and provided with rollers II journaled on bolts I2.

A pair of tension springs I3, having their'fone ends connected to the carriage and their other ends connected to the base 5, are provided to yieldably resist downward movement'of the'carriage 9 relative to the base 6. A pair of tray-supporting rails I4 are mounted in spaced parallel relation upon the carriage 9 to receive one-or more trays It formed with upturned end walls I'I to support a plurality of notched bars I8. The upper edges of the upturned anges I1 of the trays le are notched at spaced intervals to receive the ends of the bars I8. The ends of the bars I8 are thus secured against longitudinal or lateral displacement relative to the tray, but the bars I3 may readily be lifted from the tray I5 for the purpose of transferring the bobby pins I9 onto an oven Wire 2l, as illustrated in Fig. '7 in the drawings. After the bobby pins are mounted upon the oven Wire 2 I, the notched bar I8 is removed from its position Within the loop end of the bobby pins. After the bobby pins are thus mounted in spaced parallel relation upon the oven wire 2l, they are ready for subsequent manufacturing operations, such as tempering, japanning, etc.

The carriage t is reciprocated laterally along the base 6 by means of a pair of eccentrics 22 provided on a drive shaft 23 acting through a pair of connecting rods 24. The inner ends of the connecting rods 24 are provided With apertures 26 to receive studs 2'! provided on brackets 28 which are secured to the carriage 9 by means of rivets 29. The drive shaft 23 is journaled in bearing brackets 3l having their inner ends secured to the base 6 by means of bolts 32.

Each bar iB is formed With a plurality of notches 33 along its upper edge to receive the loop portion 34 of bobby pins I9. Each notch 33 is formed with a relatively long sloping surface 36 terminating at a relatively short abutment shoulder 31. The spacing between notches 33 may be varied to suit subsequent manufacturing operations.

In the operation of the bobby pin spacing de- -vice thus described, a group of bobby pins I9 are mounted on the upper end of each bar I8, and the bars are then mounted in position upon the tray I5. The loaded trays are then placed upon the tray-supporting rails i4 of the carriage 9 which is adapted to be reciprocated at a rate of approximately 490 or 500 strokes per minute to cause the bobby pins I9 to move down their respective bars I8 until they are arranged in equally formed at spaced relation within their respective notches 33.

As illustrated in Fig. 5, each notch 33 is formed to receive and prevent movement of a single bobby pin I9 downwardly along the bar l 8. When more than one bobby pin is disposed within a notch 33, the lowest bobby pin is forced upwardly and outwardly from the notch by the pressure exerted by the adjacent following bobby pins. Within a relatively short period of time, the group of bobby pins is arranged in equally spaced relation within their respective notches 33; after which, the group of bobby pins is transferred onto an oven wire as illustrated in Fig. 7 in the drawings. i

Assignee of record is the owner of co-pending application led July 24, 1944, Serial No. 546,399 in the name of Frank D. Reynolds for Method and apparatus for spacing hair fasteners.

While this invention has been shown in but one form, it is o'bvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from, the spirit and scope of the claimed invention.

I claim as my invention:

1. A bobby pin spacing device comprising a bar to be inserted through the loop end of a group of bobby pins, said bar having a plurality of notches spaced intervals along its upper edge, a tray to support said bar in an inclined plane, a carriage to support said tray, a base to support said tray in an inclined plane, means provided on said body to suspend said carriage in an inclined plane, and means to reciprocate said carriage to move a group of bobby pins downwardly along said bar and into spaced parallel relation within said notches.

2. In a bobby pin spacing device, a base having an inclined carriage supporting surface, a carriage supported upon said base, said carriage being suspended from the upper end of said base, means to reciprocate said carriage laterally along said base, a tray mounted upon said carriage, and a plurality of bars for insertion through the loop ends of a group of bobby pins, said bars being formed with spaced notches along their upper edges to engage the lop ends of said bobby pins.
